IMPROVEMBNT'IN CARRIAGE-PROP JOINTS.

TO' ALL WHOM I'I MAY CONCERN:

Be it known that I, ELBERTSON W. WAITE, of N ew Haven, in the'StateConnecticut, have invented, made, and applied to usev a certain new anduseful Improvement in Joints for Carriage-Props; and I do hereby declarethe following to be a full, clear, and exact description of the saidinvention, reference being had to the annexed drawing, making part ofthis specification, wherein.

Figure 1 is a section of said carriage-prop joint longitudinally, and

Figures'2 end-3 represent the same edgewise of the joint and bars.

Similar marks of reference denote the some parts.

Hor'etofore the joints for carriage-props have been forged upon the endsof the barseomposing such props,

the centre pins of such joints coming outside the line of one edge ofthe bars, in order that the bars may fold down closely together, andwhen unfolded, the ends of the bars will abut together and support thecarriage-top. Joints of the aforesaid character are costly to make, anddiiiieult to finish up ina handsome manner, and these carriage-props,being in exposed positions, require to be made in such a manner as notto disfigure the carriage-top.

The nature ofmy said invention consists in o. carriage-prop made with adouble joint and link, so that the bars composing the prop can befinished externally nearlythe same as they would be'if there were nojoint, the

link entering the slot formed near each cndof the bar, and beingunitedby rivets or screws, one in each bar. Thereby a handsome, strong,durable prop is made, possessing all the folding-qualities of othercarriage-props, but with ajoint that is not prominent, as heretofore. vI

In the drawing, a and I; represent portions of the ends of the metalbars composing thecarriagc-prop. These bars are to be of any desiredlength or pattern, and in the eiid of each a recess or slot is formed bya cutter, or forged of a size to receive one portion of the link a, thatis formed with rounded ends, as shown, the screws, pins, or rivets 02forming the centre of the arcs of circles described at the ends of saidlink, and also uniting the link with, the bers,'so that the parts willturn in folding or unfolding the bars.

The pins or rivets d are towards one edge of the bars at, so that theends come-together at 2,.to support the carriage-top, and at 3 the barsare rounded at one side of the ends, so as to allow the parts to foldtogether, in the form indicated by red lines. i i r This c'nrriage propis neat and strong at the joint, and can be made for much less expensethan those before employed. I

i What I claim,'and desire to secure by Letters Patent, is

The carriage-prop, made with thelink b attached by'thepins or screws cld to the bars a and b, in the mannor and for the purposes specified.

In witness whcreofI have hereunto set my signature, this seventh day ofJuly, A. D 1868.
